...next step, obviously, would be to see if these same genes appear in mammals' or even the human genome. Chances are good: the fruit-fly genome is made up of 14,000 genes, while the human genome contains 20,000. Much of the molecular machinery underlying species as varied as flies and humans might therefore be conserved, which is why the lowly fruit fly makes a worthy model for understanding human beings, even for such complex behaviors as aggression...
...Trying to understand the relationship between a set of neurons and its behavioral output is going to be difficult unless we are able to look at an organism that is simple enough where we can use our genetic tools," says Herman Dierick, a human- and molecular-genetics expert at Baylor College of Medicine. "That's where the usefulness of flies lies. Fruit flies have made such a difference in biology over the past century." And if the recent papers are any indication, these fascinating, high-spirited and surprisingly engaging little bugs will continue to do so for a long time...

...even in lab-created packages of 20 to 50 antibodies - they seem to confer some protection against disease progression. "It's the first time that anybody's really looked at what the antibody response is," says senior investigator Michel Nussenzweig, head of the Rockefeller University's Laboratory of Molecular Immunology. "If we know what can work in nature, then the next step would be, Let's see if we can reproduce it." (See the most common hospital mishaps...
